VALVE.

SPECIFICATION forming part'of 'Letters Patent No. 274,364, dated March 20, 1883.

Application tiled November 16, 18552.

the valve proper closes againsta scatto shut uit, regulate, and otherwise control the passage for steam, liquid, and similar purposes.

My invention consists in certain improved features, hereinafter described, by means whereof a tight joint can be the better insured between the valve proper and its seat, preventing leakage, eiects of corrosion, grinding, 85e. I provide a seat of wood, and in conjunction therewith a metal valve, and as will now more fully appear.

The accompanying drawings illustrate my invention as applied to a check-valve, Figure l being a side elevation with part of the shell broken away to show the interior parts, the valve proper being raised from its seat and the arrows indicating the direction of the steam, liquid, &c. Fig. 2 is a transverse sectional elevation, showing the valve closed against its seat.

Similarletters refer to similar parts throughout the several views. l

A represents the outer or globular shell of the valve, with its inlet and outlet branches A A?, as ordinary.

B is the usual annular metal seat inside the shell, but here made countersunk to form a seat and annular shoulder to receive and retain the wood valve-seat O. The Wood seat (l is the valve-seat proper, against which the action of the stem-valve takes place. Both the countersnnk seat B and the wood seat C have their openings or passage-way in line with each other, as indicated in Fig. 2, and so that the steam or liquid, &c.,can pass through said openings. (See Fig. l.) The valve-seat C- is simply an annular-shaped piece of Wood, having opening c, and snugly tits into the surrounding metal seat B. (See Fig. 2.)

D represents a metal valve, and forming (No model.)

part of it is its stein d. This meta-l valve or disk D, I further make to have a flange at d', and tapering or bevel sides at d2. (See figures.) The purpose of both the ange and bevel sides is to obtain a twofold' means of insuring a closure of the valve D against the seat O-that is to say, the valve by its bevel contiguous sides of the wood seat, and at same time the said valve by its ange can close against the top face of the wood seat,as shown in Fig. 2.

E represents a metal sleeve, having side apertures or holes, e, through which the steam, liquid,f&c., can pass, as indicated. Thesleeve E is placed on top of the wood seat C and keeps same in place 5 also, the sleeve acts as a guide to true the closing and openin action of the stem-valve.

F is the screw-cap, having mortise f to allow yfor the automatic action of the stem-valve. The cap F closes the top part of the valve, retains the sleeve E and wood sea-t C firmly in their places.

My improved valve being constructed as shown and described, the operation is as follows: The stem-valve, in fully closing by its bevel sides and iange, acts upon the libere of the wood seat in the direction where the latter is coniined in the eountersunk seat B, and embeds its shape in the wood seat. AThe material (wood) has its nature, when subjected to steam, hot water, or liquid action, ren

-sides can be made to close against the like dered suftlciently pliable to accommodate itwear on part of the wood seat is followed up 7 by properly seating or closing the valve.

What I claim is- 1. The improved valve for steam, liquid, Sac.,

consisting essentially of a wood seat, C, and constructed to operate as and for the purposes no metal valve D, in combination with an outer set forth.
